1 This gamma dose range does not mean equipment limitation. And lower limit does not mean MDA. This highest dose range is due to the dose error by rough provided rough calibration.

2 These performance parameters are vulnerable to individual difference and individual calibration condition of sensor modules.

3 Energy compensation is not executed yet. Right now, provided calibration sheet is arranged to fit to background radiation value, cesium 134/137 radiation would be under estimated around 30%. This issue is not hardware issue, but would be resolved by some future software release.
